It would seem that the correct yoke wiring harness could be as easy to create as making an adaptor to mate the leads of the existing "roundie" yoke harness to the correct plug for the older chassis. That would leave only the correct Yoke Program and Convergence Ballast values and pinouts to be determined, since the CRT cable should be directly compatible with all 21" color tube applications.

Maybe you could get ideas for the correct adapter needs by comparing schematics of the CTC-7 (and -9, -11 etc.) with the older RCAs to see what major differences there might be. With very early color sets, there may not be too many differences from one brand to another, except the connector types.
